We investigate the structure of the fixed-point algebra of On under the action of the cyclic permutation of the generating isometries. We prove that it is ⁎-isomorphic with On, thus generalizing a result of Choi and Latrémolière on O2. As an application of the technique employed, we also describe the fixed-point algebra of O2n under the exchange automorphism.

关于Cuntz代数及其不动点代数的循环自同构

我们研究了不动点代数的结构 n在生成等距的循环排列的作用下。我们证明它是⁎-同构的n,从而将 Choi 和 Latrémolière 的结果推广到 2. 作为所采用技术的应用,我们还描述了2n 在交换自同构下。
